Hi all, i have built a nixie clock for my home cinema, now i want to ensure the nixie tubes light up only when there is sound in the room, ie someone is there to see it lit.
This is what i have built https://www.instructables.com/id/Huge-wood-nixie-clock/
This is the kit i used to power the nixies - https://www.pvelectronics.co.uk/index.php?main_page=product_info&cPath=1&products_id=59
I need to apply a 5v feed to the nixie electronics when there is no sound and 0v when there is sound. So i need to detect sound in the room, then hold a 0v pull down for a period of time(say 10mins?) and keep trigering the 10min timer period after every noise heard.
What would the best what be to do this? 555? or counter?
Cheers
Steve
